Question 54

The average monthly salary of employees, consisting of officers and workers, of an organisation is Rs 3,000. The average salary of an officer is Rs 10,000 while that of a worker is Rs 2,000 per month. If there are total 400 employees in the organisation, find the number of officers

Solution

Let number of officers be $$x$$ and number of workers be $$(400-x)$$

According to ques,

=> $$(10,000\times x)+2,000\times(400-x)=3,000\times400$$

=> $$10,000x+8,00,000-2000x=12,00,000$$

=> $$8000x=4,00,000$$

=> $$x=50$$

$$\therefore$$ Number of officers = 50

=> Ans - (B)
